AM8a Instruction Manual
6.11 SLC®96 MODE I OR II MESSAGES
When the AM8a is monitoring the RX or TX lines of a SLC®96 I or II (Mode I or Mode II) PCM
link, three additional metering displays are available. These displays are the result of the
decoding of bits in the PCM data stream.
NOTE: A SLC®96 RX line or TX line is also referred to as a "half-span" in some PCM
descriptions.
6.11.1 ALARM TX or RX: provides an indication of alarm conditions detected on the link. For
both TX and RX, there are two variations of the metering format. The one displayed is
dependent on how the monitored switch is equipped.
The upper display shows 15 conditions which can be reported by the position of an
"A". The lower display shows 10 conditions. (In an actual display both lines will
usually have the same format.)
Figure 6-6 shows the display and identifies the Alarm Conditions. This is a dynamic
display which will change as alarms occur. Alarm messages also will be printed via
the RS 232 port.
